The present invention addresses the problem of providing an optical compensation thin film which contains a cellulose acylate and an additive and which when laminated on a polarizer with a photocurable adhesive, exhibits high adhesiveness to the polarizer and can reduce the occurrence of curling and the deterioration of polarization degree. An optical compensation film which contains a cellulose acylate having an acylation degree of 2.0 to 2.5 and an additive and which has a film thickness of 15 to 40μm, characterized in that when 50pl of hydroxyethyl acrylate droplets are dropped on the film at 23ºC and 55%RH, at least one surface of the film exhibits a permeability of 10 to 25pl/15sec to the droplets. |
